Study on the Current Status and Evaluation Methods of Noise Certification for Unmanned Aerial Vehicles (UAVs)

This paper tracks the latest development of UAV noise certification regulations in various countries, outlines the current airworthiness noise requirements, focuses on the overview of various UAV noise assessment methods, and analyses the characteristics and differences of the existing UAV noise evaluation methods in terms of evaluation indicators, measurement procedures and data correction. Combined with the existing domestic environmental protection requirements and noise pollution prevention requirements, as well as the requirements of the UAV superseding law, it can be expected that the impact of UAV noise on people will be an important part of the future UAV airworthiness certification, which will be an important guiding significance for states’ legislation and standardization.
